So your equation is a composite function. It means to plug 1.5 as x into g(x), then the answer you get for that, plug into h(x).
So.
g(1.5)=8-3(1.5)
=8-4.5
=3.5
Then.
H(3.5)=2x+5
=2(3.5)+5
=7+5=12
Your final answer is 12.
The correct equation of 146 ÷ 7 = 20857 is 146.0 ÷ 7.0 = 20.857
<h3>How to divide the decimals?</h3>
The equation is given as:
146 ÷ 7 = 20857
The above equation is wrong.
The equation can be rewritten as:
146.0 ÷ 7.0 = 20857
The significant digits in 146.0 and 7.0 are 3 and 1, respectively.
3 - 1 = 2
This means that
So, the decimal place in the result must be after the second digit.
So, we have:
146.0 ÷ 7.0 = 20.857
Using the above highlights, we have:
146 ÷ 0.7 = 208.57
1.46 ÷ 7 = 0.20857
14.6 ÷ 0.7 = 20.857
1460 ÷ 70 = 20.857
The reasoning behind the above equations is that the decimal position in the results is dependent on the decimal positions in the dividend and divisor
